Robust method for camera self-calibration by an unkown planar scene
Machine Graphics & Vision, 2014 In this paper we present a self-calibration method for a CCD camera with varying intrinsic parameters based on an unknown planar scene. The advantage of our method is reducing the number of images (two images) needed to estimate the parameters of the ...

Earth and Space Science, Volume 13, Issue 5, May 2026.Abstract The Lunar Trailblazer mission aimed to assess the presence of water on the lunar surface using imaging spectroscopy in visible shortwave infrared (VSWIR) coupled with high‐resolution multispectral imaging in thermal midwave‐infrared (MWIR), captured simultaneously over the same target from orbit around the Moon with two different instruments ...

Accurate and robust feature-based homography estimation using HALF-SIFT and feature localization error weighting [PDF]
, 2016 The goal of homography estimation is to find global transformation between two images of the same scene taken from different viewpoints. The feature-based homography estimation method uses a local feature extractor, a RANSAC-like method and the Levenberg-

Fish and Fisheries, Volume 27, Issue 3, Page 627-642, May 2026.ABSTRACT Monitoring recreational fisheries is difficult: anglers are widely dispersed, gear and practices vary, and many species are involved, which leads to fragmented and scarce data. To address these issues, we developed an Artificial Intelligence (AI) pipeline that turns angler‐reported photos into standardised records of catch composition and ...

Journal of Field Robotics, Volume 43, Issue 2, Page 847-878, March 2026.ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.

Robust homography estimation based on nonlinear least squares optimization [PDF]
, 2014 The homography between image pairs is normally estimated by minimizing a suitable cost function given 2D keypoint correspondences. The correspondences are typically established using descriptor distance of keypoints.

Sensors, 2014 In this paper, we propose an automatic and sequential method for the registration of an image sequence of a road area without ignoring scene-induced motion. This method contributes to a larger work, aiming at vehicle tracking. A typical image sequence is

Water Resources Research, Volume 62, Issue 3, March 2026.Abstract GaugeCam Remote Image Manager Educational 2 (GRIME2) is a free, open‐source Windows application for water level measurement in surface water bodies using ground‐based time‐lapse imagery. We evaluated a new “stop sign” (i.e., octagon shape) calibration target and GRIME2 algorithms by comparing results to other measurement methods over a 26 ...
